PRELIMINARY AMENDMENT 
Continuation of U.S. Appln. No. 09/41 1,256 

APPENDIX 

VERSION WITH MARKINGS TO SHOW CHANGES MADE 

IN THE CLAIMS ; 

The claims are amended as follows: 

1 . (Once amended) A load handling apparatus for a counterbalance type forklift, 
comprising: 

one tillable operating lever disposed on a body of the forklift; 

a mast tiltable in an anteroposterior direction and disposed on said forklift; 

a Uftable fork disposed on said mast; 

a solenoid proportional control valve, in which a tilting speed of said mast and lifting and 
lowering speeds of said fork are controlled by a degree of opening of said solenoid proportional 
control valve, said degree of opening being proportional to a tilting angle of said operating lever; 

a switch attached to said operating lever; and 

a controller [for controlling so as to output a signal for tilting] that tilts said mast when 
said operating [level] lever is tilted and [under a state where] said switch is in a first switching 
state [operated], that [output a signal for lifting or lowering] lifts or lowers said fork when [only] 
said operating lever is [operated; and disable actions of lifting and lowering] tilted and said 
switch is in a second switching state, and that prevents lifting and lowering of said fork when 
said switch is changed from said first switching state to said second switching state [to an 
inactive condition under a state where] while said operating lever is tilted [in an tilting operation 
condition unless said operating lever is returned to a neutral condition].

Continuation of U.S. Appln. No. 09/411,256 

2. (Once amended) A load handling apparatus as claimed in claim 1, 
wherein said controller includes an inhibiting circuit for stopping the tilting action of the 
mast and the lifting or lowering action of the fork when said switch is switched from said first 
switching state to said second switching state while said operating lever is being operated.
